NRD-08Z-P4    NEW

NRD Series new control signal type of DC brushless motor drive canned centrifugal pumps have been added. Tachometer feedback (rotation speed pulse output Note 1) is possible at the same time as the pump variable input signal. It is compact, lightweight, low noise, and sealless, so there is no liquid leakage.

Flow adjustment feature and built-in drive technology
An external input signal (400 Hz ± 10% of PWM, Duty 0 – 100% Note 2)  can be used to vary the flow rate. In addition, the pump can be operated without a PWM signal. (Max operation fixed) With this circuit, the power can be connected to variable external input to operate the pump.

Note1: Open collector method Outputs at 1 pulse/rotation.
Note2: Connect the PWM control signal with an open collector (drain).

Features of NRD series

Seal-less design
The pumps are equipped with a small, lightweight canned motor encapsulated in resin. This construction requires less space than magnet pumps, while the seal-less design prevents liquid leakage.
Readily compliant with international standards
The 50V or less supply voltage is classified as compliant with international standards such as UL, CSA, CE, and GS. The DC power supply does not have a region-specific voltage or frequency, allowing for unified usage.
Multiple connection types
There are three different port connection options available, Hose Barb, NPT Thread or R Thread. Select the option that best fits your location and installation.
Flow adjustment feature and built-in drive technology
An external input signal (DC 1 to 5V) can be used to vary the flow rate. The NRD series models are also equipped with a built-in motor drive circuit. With this circuit, the power can be connected to variable external input to operate the pump.
Long life
A Brushless DC motor is employed as the pump drive. This motor design eliminates pump/motor failures due to brush wear, ensuring a service life equal to AC motors.
High temperature environments
The pump can be installed in an environment with an ambient temperature of up to 50°C. It can also pump fluids as warm as 80°C.
